Dallas Cowboys rookie Joseph Randle hadn't touched the football as a pro before DeMarco Murray suffered a knee injury last week. In Murray's place, Randle accumulated 26 total yards and scored his first career touchdown in a 31-16 win over the Washington Redskins.

Murray is listed as questionable for Week 7, which makes Randle an intriguing option in fantasy football leagues. He and Philip Tanner are the last healthy backs standing in Dallas, which could pay dividends on the waiver wire.

Overview: Rookie running back who could grab the lion's share of carries in Dallas if DeMarco Murray (knee) were forced to miss time.

Background: A fifth-round pick from Oklahoma State in the 2013 NFL draft. … hadn't received a carry in two previous games before Murray left Week 6 with a knee sprain. … at 6-0 and 198 pounds, has an unconventional frame for an NFL runner. … scored 40 touchdowns in 39 career games at OSU and left after rushing for 3,085 yards, eighth-most in program history. … has been compared to Fred Jackson for his skill set and pass-catching ability.

Numbers and trends: Scored on a one-yard run in the fourth quarter of Dallas' Week 6 win over Washington. … struggled to find running room in the same game with just 17 yards on 11 carries, but did lead the team in carries. … Murray is on pace to shatter previous career-highs in receptions, which could mean extra activity on that front for Randle.

Strengths: The allure here is in the opportunity, with Murray (knee) and Lance Dunbar (hamstring) both questionable for Week 7. … Randle was highly productive, if not explosive, at Oklahoma State and has a well-rounded skill set. … receptions can help define value, especially if he were to start and get the same number of looks as Murray. … Cowboys offense moves quickly and effectively, which increases the chances for goal-to-go situations.

Risk factors: Murray is optimistic he'll play this week, even if the team isn't quite as sold. … if healthy, Dunbar could also leapfrog Randle on the depth chart, though that looks like a big "if" at this point. … lacks the elite burst of some of the NFL's top playmakers, which is supported by his lowly rushing average (1.5 ypc) last week.

ESPN ownership: 1.4 percent.

Verdict: A clear upside grab, but for good reason; Murray is brittle and could have lingering issues, making Randle a solid bet in all league formats.
